The register line

If a brief only had room for one sentence, it should be the one that says what tone you want back. Everything else in a commission is negotiable or fillable-in by the judge; the register is the one thing only you can supply, and it is the sentence most briefs get wrong.

Describe it, do not just name it

"SPH" or "worship" or "honest" are useful shorthand, but they are shorthand for a category that different judges perform differently. The same register has different names on different sites, and even the same name covers a range from one judge's version to another's. A line that describes the tone in plain words - "blunt but not cruel," "warm and a little teasing, nothing harsh" - travels better than a label, because it tells a judge what you mean rather than which bucket to sort you into. The playful register is a good example of a tone easier to describe than to name, sitting between worship and SPH and rarely called by its own word.

Where the line goes

One sentence, early in the brief, before the specifics. It sets the frame the judge reads everything else through, so putting it last means they read the whole brief once without knowing the tone and then again with it, which is wasted effort on both sides.

What this line replaces

A well-written register line does the job that a much longer explanation of your mood, your day, or your reasons for asking would otherwise try to do. None of that context is necessary; the tone description alone gives a judge what they need to plan the clip, and the rest of the brief can stay focused on the specifics rather than justifying the request. Skipping the register line entirely is what produces the vaguest, most generic clips this market makes. A stated measurement works the same way for a different line of the brief - taking one properly first removes a whole category of guessing that has nothing to do with tone at all.

There is no equivalent step on the automated side of the market, and it is worth knowing that going in. An algorithmic score does not take a register at all, because there is no performance to tune; you get one output regardless of tone requested, which is a fine trade if consistency is what you actually want. For the same reason, an AI-generated read cannot be asked to be gentler or blunter in the way a person can - a preference for that flexibility is itself a good sign a human review, not a scored tool, is the right thing to commission, a distinction Rate Cock lays out directly if you are still deciding between the two.
